The People’s Bank of China (PBoC) has just filed a new blockchain patent for a digital wallet. The Digital Currency Research Lab wants to build a wallet that allows users to track their transactions.

The application was submitted through China’s State Intellectual Property Office (SIPO) on Friday, June 22nd. The new patent filed outlines the proposal of a digital wallet that would be used to track transaction data. The new app would be in coordination with the official, centralized digital currency issuance registration agency.

Like any of the wallets on the market, it will have multi-signature security and secure the cryptocurrencies using public and private keys.
